Medical grade means it's pure. It's super weak doses. I have ADHD but also was a speed freak, so I would like it if maybe something other than amphetamines could be looked into. Also I have seen amphetamines work very well as prescribed and for certain people with adhd it actually helps with sleep and is basically the opposite effect speed normally has. For me and a lot of others, it's fucking speed, which can for sure alleviate symptoms, but that can just make you someone who's really good at doing speed cause you're further from psychotic hyperfocus that can come with a non adhd tweeker. But to me it was still super addictive, I didn't eat and didn't sleep and it led to even worse brain stuff. Bear in mind as well that I was never prescribed anything, adhd diagnosis came after speed addiction. So I'm all over the place opinion wise, like most drugs, if it works for you it works, if it doesn't it doesn't but it can easily feel like it's working real good when it actually isn't as well.
